Guilty Food Pleasures

The Disgruntled Foodie topic got me thinking...I'd like to know what guilty food pleasures do you have? I'm not talking about weird concoctions or high end stuff. I'm talking about common foods that you're almost embarrassed to admit you like to eat! A few people mentioned their love for the orange hued Kraft M&C. That's the kind of thing I'm talking about. Sure, you'll make Coq Au Vin or roll your own Sushi but what types of common things do you like that will never go out of style in your house??
